Schloss Neuhaus, a structure on the Kühberg in Salzburg's Gnigl district, was once part of an extensive fortification system. Its origins date back to the late 12th or early 13th century.
History+
The first mention of Chunradus de nova domo in 1219 indicates the castle's early existence. In the early 14th century, the complex became property of the Prince-Archbishopric and was expanded into a fortified summer residence in 1424 under Archbishop Eberhard III. von Neuhaus. From 1508, Neuhaus served as the seat of a district court, but by 1599, it was so dilapidated that the court administrator had to move. During the Thirty Years' War, the castle played a role in Salzburg's defense. After 1650, it was made habitable again for the district court, but in 1695, it suffered severe damage from lightning and fire. Oswald Graf Thun rented the castle in 1796 and purchased it in 1811. From 1851, Neo-Gothic elements were added.
